Thanks for the response.
I'm waiting on a 74923 to come in. The dealer was told by Toro that it would not be available until May 12. The dealer also said that other than size, all the G3s have the same Turf Master tire tread vs. the Multi Trac. They even called their Toro rep and he told them them they had not seen any - at least lately - with the Multi Trac tread. The rep is who told the dealer the brochure had some misses.
I guess I'll wait until my machine is delivered and see what kind of tires are on it.
